Stavime PA 600W s MRF6VP11KHR6

[Soltisik Miroslav]

Obecne maji tranzistory napajene z 12V vetsi zkresleni nez pri dejme
tomu 28V. U vykonu radove stovky wattu uz to zrejme bude vadit.

Ale tieto namietky sa tykaju len vysokovykonovych tranzistorov.
"Spotrebaky" vacsinou na 28V ani nedosiahnu.

Vsetky ostatne namietky maju racionalne jadro :
- ak budeme vsetky moduly napajat a vykon z kazdeho modulu odvadzat cez
koaxy a konektory.
To si moze dovolit tak CERN ale nie amater, preto tie mikropasky

- rovnaky zisk mat nemusia, ak sa pouziju rozumne zlucovace (ja viem, v
CERNe pouzivaju cirkulatory...)
Otvorene zostava slovicko "rozumne" v danej situacii.

- fazova chyba v zlucovaci 
 Ano to moze byt problem, preto som vzniesol otazku na Balua, ako to
riesia vedatori.

Proste stavba takehoto PA by predstavovala z 20% stavbu a 80 % ladenia.
T.j. vyvinut lacnu a efektivnu metodiku.
U anten je to podobne a predsa tu bezal odkaz na krasnu rusku farmu.
